I heard it had 5+ new game modes (i think it was 7 but i forget >_>), CG Cutscenes or something, updated graphics/music. And some other things. I think it has like 3 new minigames (a shooting one, an eating one, and something else).

Does anyone else remember reports early on about the game having wifi? Nothing more recent has mentioned it, which is kind of disappointing. My girlfriend and I were looking forward to playing together.
